I have several boxes of small potatoes left over from a crop I grew from certified seed potatoes last summer. I would like to plant them this coming spring, (August onward) but they are already statrting to sprout. If I siply remove the sprouts now and keep them dry and in the dark, will they be suitable for planting in 12-16 weeks time? Thanks for anyones interest, Regards, Clive.

We had 6-8 potato plants grow after planting. We built up the dirt with bricks around them, but now all but two have died once covered with more dirt. I was told you could harvest once they flowered and they have been in the ground for a good two to three months. However, when we dug them up there was only two pea sized potatoes on one of the vines, which was disappointing to say the least. Any ideas?

Wait for ur plants to die off completely and then harvest meanwhile put some compost or veg peels , grass cuttings on the soil.. And if yur plant has disease I may suggest plant afresh in a fresh spot with heaps of compost and loose soil and give ur plant a bit of room.. Use season once a week and u ll be amazed by the produce:)

I had the same problem but I was growing them in winter, which season were you growing in? Generally the longer you leave the potatoes the larger they get, it should be harvest time when the plant starts to die. Give them a bit more time. Did you add any nutrients to the soil? Other than that I can't think of where you may have gone wrong, maybe the potatoes were disease infested, did the dying plants appear to be suffering from disease?

I have grown potatoes several times but never had flowers. I harvest potatoes (when I get sick of waiting for the flowers) but can't understand why everyones says "wait till it flowers". Do all varieties flower??

No, not all potato varieties flower. If you have the patience, wait until the plant dies, then you can be sure you've waited long enough. If I'm after new potatoes I start bandicooting at around the 90 day mark, or when the plant starts to look a bit ratty.

The potato plants in our pre-school are starting to die down and ready for harvest in about two weeks. The children are eager to harvest them. Can the pre-school catering cook, clean and cook the potatoes immediately after harvesting them, or do they have to cure first for 10 days? thank you Grandmother to a pre-schooler Sylvana

Sylvana - Yes, you can use the potatoes straight away. They will be delicious 'new' potatoes which just need their skins rubbed off before cooking. The drying time is to ensure that potatoes will keep in storage. It hardens the skins.

The handbook-which I provided the location to in my prior reply is not very beginner'ish but it is comprehensive covering issues you may never encounter- but you do need the reference material. I have a few thoughts to add. 1. Hilling up while the plant is growing-if you are covering leaves I find this fundamentally wrong. Leaves are specialized and designed to collect light, they are not roots. So I opt to plant my seed potatoes deep enough on day one- however I tend to have the luxury of very well airated, light soil. This means the seed potato has a steady air supply and can sense the heat from the sun even at deeper depths 2. Your seedpotatoes need all their potassium Immediately. Potatoes strangely take up all their potassium that they need really early. -and don't uptake more. If there is not enough potassium in the very early stages your potatoes might have hollow heart (looks like hollow rotting middles). Late application of potassium tends to be useless 3. Potatoes seem to respond really well to the addition of microryzal fungi - in my area we source that under pine trees in a forest- we just take some forest floor duff with a dust pan and add to the potatoe planting soil. To sum up - your seed Potatoes should be about the size of chicken eggs (if larger cut up ensuring an eye on each piece and allow a few days to heal/scab up before planting). You need to chit them(make them sprout-place in dark so they sprout). Plant in soil with Compost, a sorce of potassium and microryzal fungi. If for some reason you cannot source any compost/pottasium/microryzal fungi -plant anyhow potatoes are tough -there is still a good chance they will be Okay -depends on the condition of you soil. In my area I can water deeply once per week. Harvest when about half the leaves have fallen over as if to die. If you harvest sooner you may be compromising on size-because as long as those leaves can collect light they can store the energy in the tubers. Good luck - it is so much easier than it sounds- and all those diseases in the handbook are rare and if the plants are strong (well fed) they can manage just fine, potaoes are pretty tough root crop. In other words- you can grow potatoe.
